Sorry about that. This code compiles in 2.065 but not 2.066:

////////////// test.d /////////////
struct Proxy (T)
{
    T* ptr;

    ref deref ()
    {
        return *ptr;
    }

    alias deref this;
}

struct Test
{
    auto opIndex ()
    {
        return this;
    }
    auto opIndex (int)
    {
        return 1;
    }
}

template Elem (R)
{
    alias Elem = typeof(R.init[0]);
}

void main ()
{
    alias T = Proxy!Test;
    pragma (msg, Elem!T);
}
